Trusted EV isolation

qEV columns use size exclusion chromatography to isolate extracellular vesicles quickly and reproducibly, with effective removal of soluble proteins and lipoproteins. Available in three resin series, every column is manufactured under an ISO 13485-certified quality system and is reusable up to five times.

Product highlights:

  • Precision isolation: isolate exosomes and other extracellular vesicles from 1 mL of biofluids or cell culture media. Conveniently optimised for 1 mL sample loading volumes, a common sample volume in EV diagnostics.
  • High purity: Achieve ~99% soluble protein removal to obtain a highly purified EV isolate
  • AFC-ready: Fully compatible with the Automatic Fraction Collector (AFC) V2 for efficient and reproducible isolation. 
  • Choose your resin series: Delve into more smaller particles with the 20 nm range, isolate small EVs with the 35 nm Gen 2 series, or opt for 70 nm Gen 2 columns for greater ApoB removal. Expect longer lead times for the 20 nm range.

These cotton balls are large
Because these are so large, you only need one. They’re more expensive, but because you only need one, they go a long way. They’re worth the he price, I think. The ones I’ve bought that are cheaper & much smaller, you usually have to use 3-4 balls. Try ‘em you’ll love them!

Decent but not my favorite
I wish I hadn’t ordered such a large box of these but I’ll make them work. The little sleeve is a nice idea but my fingers still slide out when I’m using one for toner or to remove makeup. And the edges sometimes scratch my face, only the middle “pillow” part is soft. Overall very “meh” lol

Soo many less bugs using this!
Color: Black 1 Devices 2 Refills
We live right next to a pond so we always get bugs galore during the spring and summer. We tried this outside over the weekend and saw a significant drop in the bugs where we had this repellent diffuser. It doesn't have a strong smell either which is nice because some of the repellent candles we've tried before just smell way too strong. This is a great little product and I love how we can take it wherever we go. Its easy to use and the directions are easy to understand. If you're trying to keep bugs away when you are outside this product is a great solution and I highly recommend it.
